Abstract (en)
[origin: EP0418170A1] This relates to a process and an apparatus for welding together two metal parts by means of a laser beam. The apparatus comprises an optical fibre (10) for transmitting the beam and a welding head (9) comprising means (29) for focusing the beam issuing from the optical fibre, means (37) for deflecting the beam issuing from the focusing means (29) in order to focus the deflected beam onto the parts to be welded, a clearance zone (42) separating the deflection means (37) and the focal point (39) of the beam and means (14) for scavenging this clearance zone by means of a scavenging gas. <IMAGE>
